Abstract
A ventilating and silencing shutter comprises frames and shutter blades, wherein the frames comprise side frames, a top frame and a bottom frame. The ventilating and silencing shutter is characterized in that an outer cover is arranged outside the ventilating and silencing shutter, the outer cover comprises an outer cover frame, movable shutters, a parallel four-bar structure and locking mechanisms, the movable shutters are arranged outside the outer cover frame, the parallel four-bar structure is arranged on the inner side wall of the outer cover frame and connected with the movable shutters for controlling the movable shutters, and the locking mechanisms are arranged on the parallel four-bar structure. According to the ventilating and silencing shutter, the outer cover with the movable shutters is used so that the ventilating and silencing shutter not only has effects of silencing and ventilating, but also has functions of dust prevention, rain prevention and heat preservation; the parallel four-bar structure and the locking mechanisms are arranged so that the movable shutters can be flexibly controlled to be opened or closed; and the integral structure of the ventilating and silencing shutter with the outer cover enables the ventilating and silencing shutter to be applied in a wider range.
Description
Technical field
The utility model relates to a kind of shutter, particularly relates to a kind of ventilating noise reduction shutter.
Background technology
The application of ventilating noise reduction shutter in industry very extensively; Places such as the inlet port of fresh air, air return through corridor mouth, cooling tower ventilating noise reduction in some ventilation systems particularly; It can not only noise reduction, sound insulation; And can reach the effect of ventilation and heat, existing a kind of ventilating noise reduction shutter is as CN2869269Y is disclosed; It comprises frame, louvre blade; Frame is made up of side frame, top margin frame, boundary frame area, and its special character is: side frame is connected with screw or rivet with top margin frame, boundary frame area, louvre blade, and the problem of existence is: because said ventilating noise reduction shutter does not have outer cover; Thereby make this ventilating noise reduction shutter can't apply to the place that temperature, dust is had high request, also can't satisfy simultaneously industrial unit use in needs adjust the requirement of the folding degree of said ventilating noise reduction shutter according to operating states of the units.
The utility model content
The purpose of the utility model is to provide a kind of ventilating noise reduction shutter, and being used to solve existing ventilating noise reduction shutter does not have outer cover to make the little problem of range of application of ventilating noise reduction shutter.
In order to achieve the above object, the technical scheme that the utility model adopted:
A kind of ventilating noise reduction shutter is provided, and it comprises frame, louvre blade, and said frame comprises side frame, top margin frame, boundary frame area; Said louvre blade is the dihedral that Open Side Down, and the following groove of said top margin frame has the groove of a del, and the upper surface of said boundary frame area is herringbone; Said louvre blade and said top margin frame, said louvre blade and said louvre blade, said louvre blade and said boundary frame area constitute inlet channel; Said top margin frame, said louvre blade, said boundary frame area are hollow structures, fill out sound insulation, damping material in the said hollow structure, and the upper and lower wallboard of said air inlet is provided with bloop; It is characterized in that: the outside of said ventilating noise reduction shutter is designed with outer cover; Said outer cover comprises outer cover framework, movable blinds, and parallel four-bar structure, retaining mechanism, said movable blinds are arranged on outer cover framework outside; Said parallel four-bar structure is arranged on the inside wall of outer cover framework and connects the said movable blinds of control, and said retaining mechanism is arranged on said parallel four-bar structure place.
This set has the ventilating noise reduction shutter of outer cover; Because said ventilating noise reduction shutter is provided with the parallel four-bar structure; Thereby can be easy to control very flexibly the switching of said movable blinds; Because said ventilating noise reduction shutter also is provided with retaining mechanism, open and close degree simultaneously thereby can fix said movable blinds flexibly.
The beneficial effect of the utility model: the outer cover of employing activity blinds makes said ventilating noise reduction shutter not only satisfy the effect that noise reduction is ventilated, but also has effect dustproof, rainproof, insulation; Parallel four-bar structure and retaining mechanism make the switching degree of said movable blinds to control flexibly; This overall structure that has the ventilating noise reduction shutter of outer cover makes that the utilization scope of ventilating noise reduction shutter is more extensive; Can not only apply to the place that temperature, dust is had high request, and can satisfy industrial unit and adjust the requirement of the folding degree of said ventilating noise reduction shutter according to operating states of the units in using.
